IMPROVEMENT IN REVOLVING HOSE-NOZZLES.

Specification 'forming part of Letters Patent No. 56,284, dated July 10, 1866.

showing the nozzle in a straight condition for throwing a stream of water straight from the pipe. Fig. 2 is also a longitudinal section, but representing the tip of the nozzle inclined to throw the stream in a direction at an acute angle to the pipe. Fig. 3 is a plan view, showing how the tip oi' the nozzle may be placed in a line tangent to a circle concentric with the base thereof in order to produce a rotating motion of the tip by the reaction of the stream.

Similar letters of reference indicate similar parts in all the drawings.

This invention consists in constructing a revolving nozzle for hose or water-pipes with two oblique joints in such a way that the tip of the nozzle may be turned so as to throw a stream at an acute or other angle to the base of the nozzle or to the hose. j

It also consists in arranging the said oblique joints with reference to the tip and body of the nozzle in such a way that the tip may be placed at a tangent to a circle concentric with the body, so as to insure a rotary movement of the nozzle around the end of the hose by the reactive force of' the stream expelled there- 'from without the use of an extra tip.

To enable those skilled in the art to understand the construction and operation of my invention, I will proceed to describe it.

The tubular tip A is secured at b to the front or upper section, B, which is attached to the central section, (l, by an oblique joint, I. This central section, O, is, in turn, attached to the lower or rearmost section, D, by a similar joint, J, placed at an angle to the joint I, as shown in the drawings. The lower or rearmost portions of the nozzle will be presently described.

r)The joints I and J are both formed in substantially the same way, as follows: Around the upper end of the section O or the section B, as the case may, is formed a tolerably deep groove rectangular in its cross-section, and in which is placed a ring, d, which has a screwthread formed upon its outer side. The corresponding section has an annular ange, 7L, projecting from its rearmost end, which is provided with an internal screw. This flange is screwed fast upon the ring d, which is thus firmly confined in the groove and secures both sections together. The rims e, which form the upper sides of the grooves, prevent the sections from coming apart, while the rings, having a free circular movement in the grooves, allow the oblique endsof the sections to be revolved `with reference to each other in such a way that, when the longest side w of' the central section, O, is brought more or less in contact or in line with the longest sides x and e of the adjoining sections B and D the tip A will be turned over to one side at an angle greater or less, according to the position the said sections with their oblique ends may be in with regard to each other.

When the apparatus is in a straight position, as shown in Fig. l, it may be changed into the shape shown in Fig. Shy simply turning each of the sections B and O one-fourth of the way around, both being turned in the same direction. In this position the tip A is tangential. to a circle concentric with the circumference oi' the cylindrical body ot' the nozzle, so that the reaction of the stream, iowing forcibly through the tip, will cause the entire nozzle to assumea rotary motion around and upon the base secured to the end of the hose, a suitable joint to allow such rotation being formed at the rearniost end ot' the nozzle, as follows: The section D has a cylindrical flange, 7c,projecting rearward and screwed into the front end of the outer ring, f. Eis a basering, which screws upon the ferrule or the end of the hose to secure the nozzle thereto, and through which passes the short cylinder F, which has a rim, m, formed upon its rear end, which fits against the annular shoulder n in the interior oi the base-ring E, so that the front end of the cylinder F being screwed into the rear end of ring f, the upper part, P, of the base-ring is firmly held between the lower side of the ringf and the rim 'm of the cylinder E,

^ the cylinder F revolving freely Within the part P of the base-ring.

By turning the sections B C D so as to cause their longest sides to more or less approach each other the tip may be brought to any desired angle with the cylindrical body of the nozzle `between the straight forni shown in Fig. l and the acute angle represented in Fig. 2. The nozzle is thus enabled to throw Water in various directions with regard to the position of the hose.

I will here remark that the revolving nozzles heretofore constructed. having but one oblique joint, do not permit the tip to be set at an acute or even a right angle to the lower part of the nozzle.

By placing the nozzle in the shape shown in Fig. 3 the reaction of the stream issuing therefrom will cause itto assume a rotary niotion, the cylinder F revolving Within the upper part, P, of the base-ring7 the nozzle thus depressing the water in all directions when desired.

We do not claim the particular construction ofthe joints I J as herein described, nor do we limit ourselves to the use ot' that construction; but

What We claim as new7 and desire to secure by Letters Paten t, is

The double oblique swivel -joint, so constructed that the tip is susceptible of arrangement at an acute or other angle7 or in a right line with the body, or that it may be adjusted tangentially to the circumference of the body, in combination with the revolving collar F on the body of the nozzle, substantially as and for the purposes specified.
